Sneaky Clean por Thomas Loupe

Sneaky Clean is a per-site privacy tool. For each website you visit, you choose whether to automatically wipe its history, cookies, or cache when you navigate away from the tab, close the tab, or close the browser. Other sites are untouched, so there is no need to nuke your entire browser history just to clean up after one site. Toggle history, cookies, and cache independently per site from the popup. A small "ON" badge appears on the toolbar icon whenever the current site has any clearing enabled, so you always know the state at a glance. When cache clearing is enabled, Sneaky Clean also injects no-cache headers into the page's own fetch and XMLHttpRequest calls so cached responses do not linger.

No accounts. No telemetry. No data leaves your browser. Settings sync only through your own browser profile.
